# Static rustc_lint_defs::builtin::ARITHMETIC_OVERFLOW

source · `pub static ARITHMETIC_OVERFLOW: &Lint`

## Expand description

The `arithmetic_overflow`

lint detects that an arithmetic operation
will overflow.

#### §Example

ⓘ

`1_i32 << 32;`

{{produces}}

#### §Explanation

It is very likely a mistake to perform an arithmetic operation that overflows its value. If the compiler is able to detect these kinds of overflows at compile-time, it will trigger this lint. Consider adjusting the expression to avoid overflow, or use a data type that will not overflow.
